User-configurable closed-loop notifications and infusion systems incorporating same

Abstract

A system includes one or more processors, and one or more processor-readable storage media storing instructions which, when executed by the one or more processors, cause performance of: switching operation of an infusion device from a first mode of fluid delivery to a second mode of fluid delivery, the first mode being different from the second mode, receiving user input after the infusion device is operating in the second mode, the user input being indicative of whether the infusion device should remain operating in the second mode or transition from the second mode to a different mode, and operating the infusion device in a manner that is influenced by the user input.

What is claimed is:

 receiving user input after the infusion device is operating in the second mode, the user input being indicative of whether the infusion device should remain operating in the second mode or transition from the second mode to a different mode; and 
 operating the infusion device in a manner that is influenced by the user input. 
   
     
     
         2 . The system of  claim 1 , wherein switching operation of the infusion device from the first mode to the second mode is performed in response to detecting an alert condition based on obtaining, from a sensing arrangement, a sensor value for a physiological condition of a user. 
     
     
         3 . The system of  claim 2 , wherein operating the infusion device in the manner that is influenced by the user input comprises:
 transitioning from the second mode to the first mode upon determining that the sensor value corresponds to an updated glucose reference value.   
     
     
         4 . The system of  claim 2 , wherein operating the infusion device in the manner that is influenced by the user input comprises:
 identifying an anomalous condition by determining the sensor value and an updated glucose reference value differ by more than a threshold amount; and   operating the infusion device in an open-loop mode.   
     
     
         5 . The system of  claim 1 , wherein the user input is a response to a user notification provided in accordance with user-specific alert configuration information.

         10 . The method of  claim 9 , wherein operating the infusion device in the manner that is influenced by the user input comprises:
 transitioning from the second mode to the first mode upon determining that the sensor value corresponds to an updated glucose reference value.   
     
     
         11 . The method of  claim 9 , wherein operating the infusion device in the manner that is influenced by the user input comprises:
 identifying an anomalous condition by determining the sensor value and an updated glucose reference value differ by more than a threshold amount; and   operating the infusion device in an open-loop mode.   
     
     
         12 . The method of  claim 8 , wherein the user input is a response to a user notification provided in accordance with user-specific alert configuration information. 
     
     
         13 . The method of  claim 8 , wherein the first mode corresponds to a closed-loop mode.

         15 . One or more non-transitory processor-readable storage media storing instructions which, when executed by one or more processors, cause performance of:
 switching operation of an infusion device from a first mode of fluid delivery to a second mode of fluid delivery, the first mode being different from the second mode;   receiving user input after the infusion device is operating in the second mode, the user input being indicative of whether the infusion device should remain operating in the second mode or transition from the second mode to a different mode; and   operating the infusion device in a manner that is influenced by the user input.   
     
     
         16 . The one or more non-transitory processor-readable storage media of  claim 15 , wherein switching operation of the infusion device from the first mode to the second mode is performed in response to detecting an alert condition based on obtaining, from a sensing arrangement, a sensor value for a physiological condition of a user.
